Nufarm’s Dan Beran breaks down the differences in systemic, contact, residual and post-emergent weed control, and which ones your crops need to thrive.
In perennial cropping systems, weed pressures can vary greatly, spanning a broad spectrum of annual, biennial and perennial weeds from year to year. Resistant weeds are also growing in prevalence, making it increasingly important for producers to be targeted in their weed control strategies.
When determining weed control options, growers should employ multiple modes of action and a program with residual herbicides, says Dan Beran, director of CPP technical services for Nufarm, North America.
“The tree nut, vine or vegetable grower has a number of unpredictable challenges throughout the growing season – insects, diseases, irrigation, fertility,” Beran says. “They need flexibility in time management, which is where residual herbicides have the greatest benefit. They allow growers to control those weeds before they come up.”
